飞机播种豆科牧草种子是将种子直接播在干热的土壤上,须等雨后才能发芽。在这种不利环境下,如用常规拌种,则附在种子上的根瘤菌迅速死亡,达不到接菌的目的。所以,必须采用丸衣接种根瘤菌的方法。也就是在种子外面包裹一层丸衣,把根瘤菌接种在丸衣里,这样可以延长根瘤菌存活时间,减少根瘤菌死亡,有利于幼苗及早形成有效根瘤并固氮。本文通过抗干热测定及盆栽和田间试验,证明种子丸衣接菌法获得明显的增产效果。 Plane legume forage seed sowing seeds are sowed in dry and hot soil, to wait until after the rain to germinate. In this adverse environment, such as the use of conventional seed dressing, the rhizobium attached to the seeds quickly died, not to achieve the purpose of inoculation. Therefore, we must adopt the method of inoculation of Rhizobia. Which is wrapped in a layer of pillows outside the seeds, the Rhizobium inoculation in the pillows, so you can extend the survival time of rhizobia, rhizobium reduce the death, is conducive to the formation of effective early seedling nodules and nitrogen fixation. In this paper, anti-dry heat determination and potted plants and field experiments proved that the seed pills Pichia pastoris method was significantly increased yield.
